refactor: Removed trigger from RouteChoice

To avoid this:

Error: COMMIT: PRs with a single commit require the commit message to conform to the conventional commit spec.

fix: Fit and vec_evaluate can now handle dynamic routes

Simulation of static routes from dynamic routes now handled in __call__ as this avoids a situation where we have subtly different logic in __call__ compared to _simulate_static_route_selection.

Introduced _simulate_static_route_selection which simulates static routes, even when dynamic routes are being evaluated in _vec_evaluate().

This was necessary as dynamic routes use text inputs, but we use vector inputs when evaluating for increased performance.

Also refactored a little to avoid code duplication between _simulate_static_route_selection() and __call__().
